What you are describing is similar to how I was diagnosed.

I took the WAIS-IV and was told that I do not "technically" have an IQ since I have ADHD and the tests are not designed nor calibrated to measure intelligence in populations other than neurotypicals. Doesn't mean I cannot be given a score, just that it's not technically "accurate."

I am quite dubious of IQ testing to begin with. But for the sake of adding to your comment, I had 2.5 standard deviations between some of my scores. I was significantly stronger in my VCI and PRI than my WMI and PSI.
